Ophthalmologic Outcomes in Zygomaticomaxillary Fracture Repair With and Without Orbital Floor Repair.

Introduction

Orbital floor (OF) fractures accompany all zygomaticomaxillary complex (ZMC) fractures, but guidelines for repair of OF fractures in this setting are unclear.

Objectives

To compare ophthalmologic outcomes of ZMC repair with and without concurrent OF repair.

Methods

We retrospectively reviewed patients undergoing ZMC fracture repair with and without OF repair between 2016 and 2018. Patients were reviewed for demographics, preinjury characteristics, and ophthalmologic outcomes.

Results

Of 61 total patients, 32 underwent concomitant OF repair while the remaining 29 underwent ZMC repair alone. The OF repair group had increased OF fracture size, displacement in the coronal plane, and malar eminence displacement (p < 0.05). Eight patients in the OF repair group had postoperative diplopia compared with no patients in the group without OF repair (p < 0.05).

Conclusion

Retrospective analysis of ZMC fracture repair without and with OF repair did not reveal a significant difference in short-term ophthalmologic outcomes while controlling for fracture size.
